HLA antigen frequencies in flax byssinosis patients.
Not all workers exposed to flax dust contract byssinosis. It is not known what determines susceptibility or insusceptibility. This study is an attempt to establish whether the incidence of histocompatibility antigens is involved in susceptibility to the disease. Forty patients suffering from flax byssinosis were tissue-typed for HLA-A and -B antigens. HLA-B27 was significantly more common in th...
متن کاملPrevalence of byssinosis in Swedish cotton mills.
The prevalence of byssinosis and of chronic bronchitis was studied in a questionnaire investigation among workers in bale opening areas, carding rooms, and spinning rooms in five Swedish cotton mills. Airborne dust and Gram-negative bacteria was measured. Nineteen per cent of the interviewed workers reported symptoms of light byssinosis (grade 1/2). The prevalence of symptoms was not related to...
متن کاملFlax-Dust Byssinosis and Chronic Non-Tuberculous Chest Disease in Belfast
If is an appropriate time to review chronic non-tuberculous chest disease (C.N.T.C.D.). This is now one of the most important medical diseases. It is extremely common. The disability is often gross. The mortality is heavy. It can now be observed without the confusion of co-existing phthisis and without its course being cut short by broncho-pneumonia. The old background of poverty and malnutriti...
متن کاملDiscriminant function analysis as an aid to the diagnosis of flax byssinosis.
A simple discriminant function in four variates (area of mill, average number of cigarettes currently smoked per day, a complex of dyspnoea, cough, and wheezing grades, and occupation) was derived to discriminate between non-byssinotic (grade o) and byssinotic (grades I and II) preparers. This function diagnosed 14% of non-byssinotics as byssinotic and 35% of byssinotics as non-byssinotic, givi...
متن کاملDust exposure in manual flax processing in Egypt.
Manual flax processing originated in Egypt in 2 000 BC. In the present study a representative sample of the workers involved in this trade, where flax is processed in small workshops or homes, was examined, and their dust exposure was evaluated. The study showed that workers handling and processing flax are exposed to high concentrations of dust; the levels of dust at hackling and combing are c...
